BEFORE YOU BUY
Check the sensor and EH-150 installation
ACTUAL APPLICATIONS
EH-PT4 supports four-channel temperature monitoring
Install the module in an EH-150 PLC where multiple RTD points must be acquired. Sensor wiring, excitation, range selection and engineering scaling must match the process design.
-
01 · PROCESS TEMPERATURE
Measure Pt100 temperature
Connect compatible Pt100 sensors to monitor process or equipment temperature. Configure the correct range and check lead-wire effects before use. -
02 · MACHINE MONITORING
Track bearing or enclosure heat
Use separate RTD channels for selected machine locations. Confirm sensor placement, wiring integrity and alarm logic in the PLC program. -
03 · UTILITY SYSTEMS
Monitor tanks or piping
Acquire temperature from compatible Pt1000 or Pt100 sensors in utility equipment. Validate engineering units and response time during commissioning.

EH-PT4 SYSTEM INTEGRATION
Match the product data to the installed system
Hitachi EH-PT4 is an EH-150 temperature-input module with four RTD channels. It supports Pt100 and Pt1000 sensors for industrial temperature measurement.
The module provides signed 15-bit conversion and processes four inputs in approximately 0.5 seconds. Verify sensor type, wiring method, range selection, external 24 V DC supply and terminal assignment before commissioning.
Confirm the complete EH-PT4 identity, installed accessories, wiring and engineering settings. The product description alone does not establish compatibility with an existing machine.
Features:
- Four independent RTD input channels
- Pt100 and Pt1000 sensor support
- Signed 15-bit conversion data
The Hitachi EH-PT4 requires its product identity, ratings, wiring and installed configuration to be checked before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Use the complete Hitachi EH-PT4 article number when evaluating a replacement. Compare the installed hardware, accessories and documented ratings before accepting a substitute.
Record the nameplate, revision, connections, installed options and engineering settings before exchanging hardware. Preserve available backups and commissioning records.
Do not regard a similar family member as an automatic replacement. Verify mechanical fit, electrical ratings, interfaces and configuration before accepting a substitution.
Features:
- Match the complete article number and revision
- Check wiring, options and saved settings
- Revalidate the installed application
The Hitachi EH-PT4 requires replacement verification of identity, ratings, interfaces and installed configuration before commissioning.
